Description

Technical Field

[0001] This invention relates to the field of connection and fixing devices, and in particular to a connection and fixing device for steel beams at the head of concrete columns. Background Technology

[0002] In modern building construction, the connection between steel and concrete structures is an important means of achieving the force and load transfer of the composite structure. Especially in prefabricated buildings, high-rise frame structures and industrial plants, the connection quality between concrete column heads and steel beams is directly related to the stability and load-bearing capacity of the entire building system. Traditional connection methods often use bolt connections, welding or embedded parts connections.

[0003] In practice, some problems still exist: During hoisting operations, there is often a lack of effective auxiliary adjustment mechanisms, making it difficult to accurately control the lifting height and angle of steel components. Installers need to adjust the position multiple times, which is time-consuming and labor-intensive. Especially in high-altitude or confined spaces, the construction is difficult and carries a high operational risk. At the same time, most existing structures are fixed connections and lack quick locking or quick disassembly mechanisms, resulting in a cumbersome and inefficient hoisting preparation process, which seriously affects the construction progress. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a concrete column head steel beam connection and fixing device to address the shortcomings of the prior art.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a steel beam connection and fixing device for concrete column heads, comprising: a steel beam connection and fixing device body, multiple through holes, an auxiliary docking mechanism and a hoisting auxiliary mechanism, wherein the multiple through holes are provided on the steel beam connection and fixing device body, and the auxiliary docking mechanism and the hoisting auxiliary mechanism are both installed on the steel beam connection and fixing device body.

[0006] The beneficial effects of adopting the technical solution of this invention are that, through the set hoisting auxiliary mechanism, it is convenient for workers to manually pre-adjust before hoisting, which enhances the adaptability of the steel beam connection and fixing device body under different construction conditions. The overall structure is easy to disassemble and reuse quickly, which is conducive to the control of construction costs and the efficient scheduling of equipment. At the same time, three perforations are set at the bottom of the steel beam connection and fixing device body. When the connection and fixing device is placed at the column head and concrete is poured, the concrete can penetrate through the perforations and wrap the lower part of the steel component, making the connection interface tighter, enhancing the overall structural strength and durability, avoiding the generation of structural voids, and effectively improving the stability and safety of the fixing effect. The auxiliary docking mechanism significantly improves the alignment accuracy and construction safety of the concrete column head and steel beam during the connection process. It allows the concrete column head to move flexibly within a certain range to match the site structure, achieving precise fit, reducing docking errors, and helping construction personnel to promptly detect installation abnormalities and make adjustments, avoiding rework. This structure requires no electronic devices, is intuitive to operate, and is low in cost. It is suitable for complex construction sites, has strong environmental adaptability and reusability, and the overall structure makes the connection and positioning of the steel beam and column head more reliable and accurate, effectively preventing structural displacement caused by construction errors.

[0007] Furthermore, the auxiliary docking mechanism includes a docking plate, a detection mechanism, and a first locking mechanism. The docking plate is slidably mounted on the main body of the steel beam connecting and fixing device, the detection mechanism is slidably mounted on the docking plate, and the first locking mechanism is mounted on the docking plate.

[0008] The beneficial effects of adopting the above-mentioned further technical solution are that, through the set auxiliary docking mechanism, the alignment accuracy and construction safety of the concrete column head and steel beam during the connection process are significantly improved. The docking plate is connected to the sliding support through the limiting groove, which allows it to move flexibly within a certain range to match the site structure, achieve precise fitting, and reduce docking errors. The embedded detection plate and the marking groove form an intuitive installation status feedback mechanism. When the back plate is subjected to abnormal force due to improper installation or structural misalignment during the docking process, the detection plate will automatically protrude from the marking groove, thereby providing a clear visual prompt. This helps construction personnel to detect installation abnormalities in a timely manner and make adjustments to avoid rework. This structure does not require the participation of electronic devices, is intuitive to operate, and has low cost. It is suitable for complex construction sites, has strong environmental adaptability and reusability. The overall structure makes the connection and positioning of the steel beam and column head more reliable and accurate, effectively preventing structural displacement caused by construction errors.

[0009] Furthermore, the steel beam connecting and fixing device body is provided with a limiting groove, the docking plate is provided with a sliding groove, a sliding block is slidably installed in the sliding groove, the sliding block is connected to a sliding support, and the sliding support is slidably installed in the limiting groove.

[0010] The beneficial effects of adopting the above-mentioned further technical solution are that, through the set auxiliary docking mechanism, the alignment accuracy and construction safety of the concrete column head and steel beam during the connection process are significantly improved. The docking plate is connected to the sliding support through the limiting groove, which allows it to move flexibly within a certain range to match the site structure, achieve precise fitting, and reduce docking errors. The embedded detection plate and the marking groove form an intuitive installation status feedback mechanism. When the back plate is subjected to abnormal force due to improper installation or structural misalignment during the docking process, the detection plate will automatically protrude from the marking groove, thereby providing a clear visual prompt. This helps construction personnel to detect installation abnormalities in a timely manner and make adjustments to avoid rework. This structure does not require the participation of electronic devices, is intuitive to operate, and has low cost. It is suitable for complex construction sites, has strong environmental adaptability and reusability. The overall structure makes the connection and positioning of the steel beam and column head more reliable and accurate, effectively preventing structural displacement caused by construction errors. Limiting grooves are located on both sides of the steel beam connection and fixing device, serving as guide rails for the sliding support. This ensures a stable movement trajectory for the sliding support during structural installation or adjustment. This sliding connection structure absorbs construction errors, improves the degree of freedom in component docking, and limits its range of movement to prevent deviation from the design position. Guided by the limiting grooves, the sliding support allows for fine-tuning of components without additional tools, improving the overall assembly efficiency and stability of the structure. The cooperation between the sliding block and the sliding groove allows the docking plate to move smoothly and precisely along the sliding path during installation, facilitating precise alignment by construction personnel based on the building structure's location. The fixed connection between the sliding support and the sliding block provides integrated structural support, improving the uniformity of force distribution within the sliding groove and preventing localized friction or jamming, ensuring smooth and stable operation of the docking plate throughout the installation process. This structure further enhances the reliability of the auxiliary docking mechanism.

[0011] Furthermore, the testing mechanism includes: a testing plate, a marking block, a scale plate, a back plate, and a marking groove. The testing plate is fixedly connected to the back plate, the back plate is slidably mounted on the docking plate, the marking groove is disposed on the docking plate, the testing plate is slidably mounted in the marking groove, the marking block is mounted on the testing plate, and the scale plate is mounted on the docking plate.

[0012] The beneficial effects of adopting the above-mentioned further technical solution are that the detection plate and the back plate form a stable structure through a fixed connection. During the contact and docking process between the steel beam connection fixing device and the building, the detection plate can realize displacement indication by means of the deformation generated by the back plate, which has good sensitivity and structural responsiveness. When inaccurate docking is not achieved, the squeezing force generated by the building surface on the back plate will be transmitted to the detection plate through the connection structure, causing it to slide along the middle of the docking plate and bulge out from the marking groove, thereby forming a clear visual warning signal to assist construction personnel in judging the connection status and improve the accuracy and safety of docking operations. The marking groove, as the embedded channel of the detection plate, can accurately limit the sliding direction of the detection plate and provide a visual feedback window. When the detection plate bulges outward due to incomplete docking, its exposed part will be clearly visible from the marking groove, allowing construction personnel to quickly judge whether there is a deviation in the connection with the naked eye. This structure can achieve efficient detection without electronic sensors, is suitable for complex construction environments, and has the advantages of low cost, intuitive identification, and timely response. It is an important component of this invention to improve the accuracy and safety of connections.

[0013] Furthermore, the first locking mechanism includes: a screw, a locking block, a threaded hole, and an extension plate. The extension plate is connected to the mating plate, the threaded hole is disposed on the extension plate, the screw is connected to the threaded hole, the locking block is connected to the screw, and the locking block is located adjacent to the body of the steel beam connecting and fixing device.

[0014] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the extension plate is set at one end of the docking plate to extend the adjustment range of the connection structure. The threaded hole on it provides a stable installation interface for the screw. The screw achieves longitudinal advance and retraction adjustment through the threaded engagement with the threaded hole, and can be fine-tuned according to the actual docking error, thereby enabling the locking block to fit more tightly with the body of the steel beam connection and fixing device. This adjustment structure is simple in design and precise in adjustment, which helps to ensure the smooth progress of the docking process and improves the adaptability and reliability of the body of the steel beam connection and fixing device. The locking block is fixedly connected to the end of the screw. When the screw is screwed into the threaded hole of the extension plate, the locking block will gradually move closer to the body until it fits, realizing end positioning and locking. The locking block fits against the outside of the body of the steel beam connection and fixing device, which can effectively prevent the docking plate from sliding backward after adjustment, improving the connection stability. This structure can be locked directly by rotating the screw without disassembling other components, which is simple and reliable, and further enhances the anti-interference ability and seismic performance of the body of the steel beam connection and fixing device.

[0015] Furthermore, the hoisting auxiliary mechanism includes: an adjustment mechanism, a second locking mechanism, a fixed base, a connecting member, and a base plate. The connecting member is connected to the fixed base, the fixed base is connected to the base plate through the adjustment mechanism, and the second locking mechanism is connected to the base plate.

[0016] The beneficial effects of adopting the above-mentioned further technical solutions are that, through the setting of the hoisting auxiliary mechanism, the cooperation between the fixed seat and the installation handle also facilitates manual pre-adjustment by the staff before hoisting, enhances the adaptability of the steel beam connection and fixing device body under different construction conditions, and the overall structure is easy to disassemble and reuse quickly, which is conducive to the control of construction costs and the efficient scheduling of equipment.

[0017] Furthermore, the adjustment mechanism includes: a mounting handle, an adjusting rod, a mounting component, a locking nut, and a limiting component. The limiting component is connected to the fixed base. The mounting handle is connected to the limiting component through the mounting component. The top of the adjusting rod is connected to the mounting component. The bottom of the adjusting rod is sleeved on the base plate. The locking nut is installed on the top of the adjusting rod and abuts against the mounting component.

[0018] The beneficial effects of adopting the above-mentioned further technical solutions are that, through the setting of the hoisting auxiliary mechanism, the cooperation between the fixed seat and the installation handle facilitates manual pre-adjustment by workers before hoisting, enhancing the adaptability of the steel beam connection and fixing device under different construction conditions. The overall structure is easy to disassemble and reuse quickly, which is conducive to controlling construction costs and efficiently scheduling equipment. The installation handle is used to assist construction personnel in handling, adjusting, and initially aligning the connection and fixing device, facilitating on-site operation. The installation handle has an installation component in the middle, which is connected to the adjusting rod by bolts, making the overall structure more stable. The two ends of the adjusting rod are fixedly connected to bolts, which can adjust the height, angle, or tightness of the installation component, thereby further improving the installation flexibility of the hoisting mechanism. The overall structure is intuitive to operate and easy to adjust, making it particularly suitable for use on construction sites where the docking position is difficult to control precisely.

[0019] Furthermore, the adjusting rod has a U-shaped structure, and a bolt is provided at the top of the adjusting rod. The adjusting rod passes through the mounting component through the bolt, and the locking nut is connected to the bolt. The mounting component is located in the middle of the mounting handle.

[0020] The beneficial effects of adopting the above-mentioned further technical solution are that, after the two bolts penetrate the mounting component, bidirectional limiting and fixing are achieved through the locking nut set in the middle, which can effectively prevent the mounting component from loosening when subjected to hoisting tension or vibration. The bottom end of the locking nut fits against the top end of the mounting component, enhancing the overall tightness and shear strength of the connection and improving the structural stress performance. This threaded locking method has good adjustability and reusability, which helps to make detailed adjustments according to different construction needs, enhancing the versatility of the equipment and its adaptability to the site.

[0021] Furthermore, the second locking mechanism includes a locking plate, a pin, and a locking rod. The locking plate is slidably connected to the base plate. One end of the pin passes through the base plate and the locking plate and is located on the outside. The locking rod is slidably installed on one end of the pin. The base plate is installed on the body of the steel beam connecting and fixing device. The body of the steel beam connecting and fixing device is provided with a sliding groove. The bottom of the locking plate is slidably installed in the sliding groove.

[0022] The beneficial effects of adopting the above-mentioned further technical solution are that the sliding groove, as the guide structure of the locking plate, ensures that it can slide stably between the base plate and the steel beam connection and fixing device without the risk of shaking or dislocation. This helps to achieve fine-tuning and rapid positioning of the hoisting position. The sliding connection method avoids the rigid structure of traditional fixed connections, making the operation more flexible and adaptable to complex construction environments. The locking plate can be adjusted within the sliding groove to meet different height or angle requirements. Combined with the pin, it can further achieve rapid locking, making the operation simple and efficient. The setting of the pin and locking rod makes the locking operation of the entire steel beam connection and fixing device simple and reliable. The pin passes through the base plate and the locking plate in sequence, and can be quickly inserted to complete the limit when needed, and can also be quickly pulled out when removing or adjusting, greatly improving the assembly and disassembly efficiency. The locking rod set at the end of the pin prevents the pin from accidentally falling off during use through a vertical sliding connection method. It is also easy to push manually or with tools, realizing the quick installation and disassembly function of the hoisting auxiliary mechanism 4, improving the practicality of the equipment and the convenience of construction.

[0023] Furthermore, there are two auxiliary docking mechanisms and two hoisting auxiliary mechanisms. The two auxiliary docking mechanisms are located on the same side of the steel beam connecting and fixing device body, and the two hoisting auxiliary mechanisms are located on the top of the steel beam connecting and fixing device body.

[0024] The beneficial effect of adopting the above-mentioned further technical solution is that the position design of the auxiliary docking mechanism and the hoisting auxiliary mechanism facilitates hoisting and the connection between the concrete column head and the steel beam.

[0044] like Figures 1 to 10 As shown, an embodiment of the present invention provides a steel beam connection and fixing device for concrete column heads, including: a steel beam connection and fixing device body 1, multiple through holes 2, an auxiliary docking mechanism 3, and a hoisting auxiliary mechanism 4. The multiple through holes 2 are disposed on the steel beam connection and fixing device body 1, and the auxiliary docking mechanism 3 and the hoisting auxiliary mechanism 4 are both installed on the steel beam connection and fixing device body 1.

[0045] The beneficial effects of adopting the technical solution of this invention are that, through the set hoisting auxiliary mechanism, it is convenient for workers to manually pre-adjust before hoisting, which enhances the adaptability of the steel beam connection and fixing device body under different construction conditions. The overall structure is easy to disassemble and reuse quickly, which is conducive to the control of construction costs and the efficient scheduling of equipment. At the same time, three perforations are set at the bottom of the steel beam connection and fixing device body. When the connection and fixing device is placed at the column head and concrete is poured, the concrete can penetrate through the perforations and wrap the lower part of the steel component, making the connection interface tighter, enhancing the overall structural strength and durability, avoiding the generation of structural voids, and effectively improving the stability and safety of the fixing effect. The auxiliary docking mechanism significantly improves the alignment accuracy and construction safety of the concrete column head and steel beam during the connection process. It allows the concrete column head to move flexibly within a certain range to match the site structure, achieving precise fit, reducing docking errors, and helping construction personnel to promptly detect installation abnormalities and make adjustments, avoiding rework. This structure requires no electronic devices, is intuitive to operate, and is low in cost. It is suitable for complex construction sites, has strong environmental adaptability and reusability, and the overall structure makes the connection and positioning of the steel beam and column head more reliable and accurate, effectively preventing structural displacement caused by construction errors.

[0046] like Figures 1 to 10 As shown, the auxiliary docking mechanism 3 further includes a docking plate 302, a detection mechanism, and a first locking mechanism. The docking plate 302 is slidably mounted on the main body 1 of the steel beam connection and fixing device, the detection mechanism is slidably mounted on the docking plate 302, and the first locking mechanism is mounted on the docking plate 302.

[0047] The beneficial effects of adopting the above-mentioned further technical solution are that, through the set auxiliary docking mechanism, the alignment accuracy and construction safety of the concrete column head and steel beam during the connection process are significantly improved. The docking plate is connected to the sliding support through the limiting groove, which allows it to move flexibly within a certain range to match the site structure, achieve precise fitting, and reduce docking errors. The embedded detection plate and the marking groove form an intuitive installation status feedback mechanism. When the back plate is subjected to abnormal force due to improper installation or structural misalignment during the docking process, the detection plate will automatically protrude from the marking groove, thereby providing a clear visual prompt. This helps construction personnel to detect installation abnormalities in a timely manner and make adjustments to avoid rework. This structure does not require the participation of electronic devices, is intuitive to operate, and has low cost. It is suitable for complex construction sites, has strong environmental adaptability and reusability. The overall structure makes the connection and positioning of the steel beam and column head more reliable and accurate, effectively preventing structural displacement caused by construction errors.

[0049] The beneficial effects of adopting the above-mentioned further technical solution are that, through the set auxiliary docking mechanism, the alignment accuracy and construction safety of the concrete column head and steel beam during the connection process are significantly improved. The docking plate is connected to the sliding support through the limiting groove, which allows it to move flexibly within a certain range to match the site structure, achieve precise fitting, and reduce docking errors. The embedded detection plate and the marking groove form an intuitive installation status feedback mechanism. When the back plate is subjected to abnormal force due to improper installation or structural misalignment during the docking process, the detection plate will automatically protrude from the marking groove, thereby providing a clear visual prompt. This helps construction personnel to detect installation abnormalities in a timely manner and make adjustments to avoid rework. This structure does not require the participation of electronic devices, is intuitive to operate, and has low cost. It is suitable for complex construction sites, has strong environmental adaptability and reusability. The overall structure makes the connection and positioning of the steel beam and column head more reliable and accurate, effectively preventing structural displacement caused by construction errors. Limiting grooves are located on both sides of the steel beam connection and fixing device, serving as guide rails for the sliding support. This ensures a stable movement trajectory for the sliding support during structural installation or adjustment. This sliding connection structure absorbs construction errors, improves the degree of freedom in component docking, and limits its range of movement to prevent deviation from the design position. Guided by the limiting grooves, the sliding support allows for fine-tuning of components without additional tools, improving the overall assembly efficiency and stability of the structure. The cooperation between the sliding block and the sliding groove allows the docking plate to move smoothly and precisely along the sliding path during installation, facilitating precise alignment by construction personnel based on the building structure's location. The fixed connection between the sliding support and the sliding block provides integrated structural support, improving the uniformity of force distribution within the sliding groove and preventing localized friction or jamming, ensuring smooth and stable operation of the docking plate throughout the installation process. This structure further enhances the reliability of the auxiliary docking mechanism.

[0050] like Figures 1 to 10 As shown, the detection mechanism further includes: a detection plate 303, a marking block 304, a scale plate 305, a back plate 307, and a marking groove 313.

[0051] The beneficial effects of adopting the above-mentioned further technical solution are that the detection plate and the back plate form a stable structure through a fixed connection. During the contact and docking process between the steel beam connection fixing device and the building, the detection plate can realize displacement indication by means of the deformation generated by the back plate, which has good sensitivity and structural responsiveness. When inaccurate docking is not achieved, the squeezing force generated by the building surface on the back plate will be transmitted to the detection plate through the connection structure, causing it to slide along the middle of the docking plate and bulge out from the marking groove, thereby forming a clear visual warning signal to assist construction personnel in judging the connection status and improve the accuracy and safety of docking operations.

When the detection plate bulges outward due to incomplete docking, its exposed part will be clearly visible from the marking groove, allowing construction personnel to quickly judge whether there is a deviation in the connection with the naked eye. This structure can achieve efficient detection without electronic sensors, is suitable for complex construction environments, and has the advantages of low cost, intuitive identification, and timely response. It is an important component of this invention to improve the accuracy and safety of connections.

[0052] like Figures 1 to 10 As shown, the first locking mechanism further includes: a screw 310, a locking block 311, a threaded hole 312, and an extension plate 314.

The locking block 311 is connected to the screw 310. The locking block 311 is located adjacent to the steel beam connecting and fixing device body 1.

[0053] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the extension plate is set at one end of the docking plate to extend the adjustment range of the connection structure. The threaded hole on it provides a stable installation interface for the screw. The screw achieves longitudinal advance and retraction adjustment through the threaded engagement with the threaded hole, and can be fine-tuned according to the actual docking error, thereby enabling the locking block to fit more tightly with the body of the steel beam connection and fixing device. This adjustment structure is simple in design and precise in adjustment, which helps to ensure the smooth progress of the docking process and improves the adaptability and reliability of the body of the steel beam connection and fixing device. The locking block is fixedly connected to the end of the screw. When the screw is screwed into the threaded hole of the extension plate, the locking block will gradually move closer to the body until it fits, realizing end positioning and locking. The locking block fits against the outside of the body of the steel beam connection and fixing device, which can effectively prevent the docking plate from sliding backward after adjustment, improving the connection stability. This structure can be locked directly by rotating the screw without disassembling other components, which is simple and reliable, and further enhances the anti-interference ability and seismic performance of the body of the steel beam connection and fixing device.

The connecting member 408 is connected to the fixed base 407, the fixed base 407 is connected to the base plate 413 through the adjustment mechanism, and the second locking mechanism is connected to the base plate 413.

[0055] The beneficial effects of adopting the above-mentioned further technical solutions are that, through the setting of the hoisting auxiliary mechanism, the cooperation between the fixed seat and the installation handle also facilitates manual pre-adjustment by the staff before hoisting, enhances the adaptability of the steel beam connection and fixing device body under different construction conditions, and the overall structure is easy to disassemble and reuse quickly, which is conducive to the control of construction costs and the efficient scheduling of equipment.

The limiting component 412 is connected to the fixed base 407. The mounting handle 401 is connected to the limiting component 412 through the mounting component 410. The top of the adjusting rod 406 is connected to the mounting component 410. The bottom of the adjusting rod 406 is sleeved on the base plate 413. The locking nut 411 is installed on the top of the adjusting rod 406 and abuts against the mounting component 410.

[0057] The beneficial effects of adopting the above-mentioned further technical solutions are that, through the setting of the hoisting auxiliary mechanism, the cooperation between the fixed seat and the installation handle facilitates manual pre-adjustment by workers before hoisting, enhancing the adaptability of the steel beam connection and fixing device under different construction conditions. The overall structure is easy to disassemble and reuse quickly, which is conducive to controlling construction costs and efficiently scheduling equipment. The installation handle is used to assist construction personnel in handling, adjusting, and initially aligning the connection and fixing device, facilitating on-site operation. The installation handle has an installation component in the middle, which is connected to the adjusting rod by bolts, making the overall structure more stable. The two ends of the adjusting rod are fixedly connected to bolts, which can adjust the height, angle, or tightness of the installation component, thereby further improving the installation flexibility of the hoisting mechanism. The overall structure is intuitive to operate and easy to adjust, making it particularly suitable for use on construction sites where the docking position is difficult to control precisely.

The adjusting rod 406 passes through the mounting member 410 through the bolt 409, and the locking nut 411 is connected to the bolt 409. The mounting member 410 is located in the middle of the mounting handle 401.

[0059] The beneficial effects of adopting the above-mentioned further technical solution are that, after the two bolts penetrate the mounting component, bidirectional limiting and fixing are achieved through the locking nut set in the middle, which can effectively prevent the mounting component from loosening when subjected to hoisting tension or vibration. The bottom end of the locking nut fits against the top end of the mounting component, enhancing the overall tightness and shear strength of the connection and improving the structural stress performance. This threaded locking method has good adjustability and reusability, which helps to make detailed adjustments according to different construction needs, enhancing the versatility of the equipment and its adaptability to the site.

[0060] like Figures 1 to 10 As shown, the second locking mechanism further includes a locking plate 403, a pin 404, and a locking rod 405. The locking plate 403 is slidably connected to the base plate 413. One end of the pin 404 passes through the base plate 413 and the locking plate 403 and is located on the outside. The locking rod 405 is slidably installed on one end of the pin 404. The base plate 413 is installed on the steel beam connecting and fixing device body 1. The steel beam connecting and fixing device body 1 is provided with a sliding groove 402. The bottom of the locking plate 403 is slidably installed in the sliding groove 402.

[0061] The beneficial effects of adopting the above-mentioned further technical solution are that the sliding groove, as the guide structure of the locking plate, ensures that it can slide stably between the base plate and the steel beam connection and fixing device without the risk of shaking or dislocation. This helps to achieve fine-tuning and rapid positioning of the hoisting position. The sliding connection method avoids the rigid structure of traditional fixed connections, making the operation more flexible and adaptable to complex construction environments. The locking plate can be adjusted within the sliding groove to meet different height or angle requirements. Combined with the pin, it can further achieve rapid locking, making the operation simple and efficient. The setting of the pin and locking rod makes the locking operation of the entire steel beam connection and fixing device simple and reliable. The pin passes through the base plate and the locking plate in sequence, and can be quickly inserted to complete the limit when needed, and can also be quickly pulled out when removing or adjusting, greatly improving the assembly and disassembly efficiency. The locking rod set at the end of the pin prevents the pin from accidentally falling off during use through a vertical sliding connection method. It is also easy to push manually or with tools, realizing the quick installation and disassembly function of the hoisting auxiliary mechanism 4, improving the practicality of the equipment and the convenience of construction.

[0062] like Figures 1 to 10 As shown, there are two auxiliary docking mechanisms 3 and two hoisting auxiliary mechanisms 4. The two auxiliary docking mechanisms 3 are located on the same side of the steel beam connecting and fixing device body 1, and the two hoisting auxiliary mechanisms 4 are located on the top of the steel beam connecting and fixing device body 1.

[0063] The beneficial effect of adopting the above-mentioned further technical solution is that the position design of the auxiliary docking mechanism and the hoisting auxiliary mechanism facilitates hoisting and the connection between the concrete column head and the steel beam.

[0064] To address the problems of difficult hoisting and adjustment, lack of quick-locking structure, low construction efficiency, and high risk associated with traditional steel beam connection and fixing devices, a concrete column head steel beam connection and fixing device is proposed.

[0065] The beneficial effects of this invention are In this invention, the lifting auxiliary mechanism facilitates manual pre-adjustment of the fixing seat 407 and the installation handle 401 by the workers before lifting, enhancing the adaptability of the steel beam connection fixing device body 1 under different construction conditions. The overall structure is easy to disassemble and reuse, which is beneficial to the control of construction costs and the efficient scheduling of equipment. At the same time, three through holes 2 are provided at the bottom of the steel beam connection fixing device body 1. When the connection fixing device is placed at the column head and concrete is poured, the concrete can penetrate through the through holes 2 and wrap the lower part of the steel component, making the connection interface tighter, enhancing the overall structural strength and durability, avoiding structural voids, and effectively improving the stability and safety of the fixing effect.

[0066] In this invention, the auxiliary docking mechanism 3 significantly improves the alignment accuracy and construction safety of the concrete column head and steel beam during the connection process. The docking plate 302 is connected to the sliding support 308 through the limiting groove 301, allowing it to move flexibly within a certain range to match the on-site structure, achieving precise fit and reducing docking errors. The embedded cooperation of the detection plate 303 and the marking groove 313 constitutes an intuitive installation status feedback mechanism. When the back plate experiences abnormal stress due to improper installation or structural misalignment during the docking process, the detection plate 303 will automatically protrude from the marking groove 313, providing a clear visual indication. This helps construction personnel to promptly detect installation abnormalities and make adjustments, avoiding rework. This structure requires no electronic intervention, is intuitive to operate, and is low in cost. It is suitable for complex construction sites, has strong environmental adaptability and reusability. The overall structure makes the connection and positioning of the steel beam and column head more reliable and precise, effectively preventing structural displacement caused by construction errors. At the same time, the three through holes 2 opened at the bottom of the steel beam connection and fixing device body 1 play a key role in the concrete pouring process. Concrete can enter the inner cavity and surrounding gap area of ​​the steel beam connection and fixing device body 1 through the through holes 2, making the contact surface between the steel beam connection and fixing device body 1 and the concrete column head more compact and firm, thereby improving the overall load-bearing capacity and durability of the structure and ensuring a stable and reliable connection after installation.

[0067] The present invention provides a concrete column head steel beam connection and fixing device, including a steel beam connection and fixing device body 1, three through holes 2 on the outer side of the steel beam connection and fixing device body 1, a hoisting auxiliary mechanism 4 on the top of the steel beam connection and fixing device body 1, and an auxiliary docking mechanism 3 on one side of the steel beam connection and fixing device body 1.

[0068] The hoisting auxiliary mechanism 4 includes: an adjusting rod 406, a locking plate 403, a base plate 413, a fixed seat 407, and a connector 408. The top end of the fixed seat 407 is fixedly connected to the bottom end of the connector 408. The bottom of the adjusting rod 406 is sleeved on the inner side of the base plate 413. The locking plate 403 is slidably connected to the inner wall of the base plate 413.

[0069] The auxiliary docking mechanism 3 includes a docking plate 302, a detection plate 303, and a back plate 307. The detection plate 303 is slidably connected to the middle of the docking plate 302, and one end of the detection plate 303 is fixedly connected to the inner side of the back plate 307.

[0070] It should be noted that in the above components, the detection plate 303 and the back plate 307 are fixedly connected to form a stable structure. During the contact and docking process between the steel beam connection and fixing device body 1 and the building, the detection plate 303 can realize displacement indication by means of the deformation generated by the back plate 307, which has good sensitivity and structural responsiveness. When accurate docking is not achieved, the pressure exerted by the building surface on the back plate 307 will be transmitted to the detection plate 303 through the connection structure, causing it to slide along the middle of the docking plate 302 and protrude from the marking groove 313, thereby forming a clear visual warning signal to assist construction personnel in judging the connection status and improve the accuracy and safety of docking operations.

[0071] Specifically, such as Figures 1 to 9 As shown, a sliding groove 402 is provided at the top of the main body 1 of the steel beam connection and fixing device, and a locking plate 403 is slidably connected to the inner wall of the sliding groove 402.

[0072] It should be noted that in the above components, the sliding groove 402 serves as a guide structure for the locking plate 403, ensuring that it can slide stably between the base plate 413 and the steel beam connection and fixing device body 1 without the risk of shaking or dislocation. This helps to achieve fine-tuning of the hoisting position and rapid positioning. The sliding connection method avoids the rigid structure brought about by the traditional fixed connection, making the operation more flexible and adaptable to complex construction environments. The locking plate 403 can be positioned according to different height or angle requirements by adjusting within the sliding groove 402. It can also be used with the pin 404 to achieve rapid locking, making the operation simple and efficient.

[0073] Specifically, such as Figures 1 to 9As shown, a pin 404 is provided on the outer side of the locking plate 403. One end of the pin 404 passes through the base plate 413 and the locking plate 403 in sequence, and a locking rod 405 is vertically slidably connected to one end of the pin 404.

[0074] It should be noted that, among the aforementioned components, the pin 404 and locking rod 405 make the locking operation of the entire steel beam connection and fixing device body 1 simple and reliable. The pin 404 passes through the base plate 413 and the locking plate 403 in sequence, and can be quickly inserted to complete the limit when needed, and can also be quickly pulled out when disassembling or adjusting, greatly improving the efficiency of assembly and disassembly. The locking rod 405 at the end of the pin 404 prevents the pin 404 from accidentally falling off during use through a vertical sliding connection, and is also easy to push manually or with tools, realizing the quick installation and disassembly function of the hoisting auxiliary mechanism 4, improving the practicality of the equipment and the convenience of construction.

[0075] Specifically, such as Figures 1 to 9 As shown, a mounting handle 401 is connected to the back of the fixed base 407, a limiting member 412 is fixedly connected to the back of the fixed base 407, a mounting member 410 is connected to the middle of the mounting handle 401, the mounting member 410 is connected to the limiting member 412, and bolts 409 are fixedly connected to both ends of the adjusting rod 406.

[0076] It should be noted that, among the aforementioned components, the mounting handle 401 assists construction personnel in handling, adjusting, and initially aligning the connecting and fixing device, facilitating on-site operation. The mounting handle 401 has a mounting component 410 in its middle, which is connected to the adjusting rod 406 via bolts 409, making the overall structure more stable. The two ends of the adjusting rod 406 are fixedly connected to the bolts 409, allowing adjustment of the height, angle, or tightness of the mounting component 410, thereby further enhancing the installation flexibility of the hoisting mechanism. The overall structure is intuitive to operate and easy to adjust, making it particularly suitable for construction sites where precise control of the docking position is difficult.

[0077] Specifically, such as Figures 1 to 9 As shown, both bolts 409 penetrate the mounting part 410, and both bolts 409 are threaded with locking nuts 411 in the middle. The bottom ends of both locking nuts 411 are attached to the top of the mounting part 410.

[0078] It should be noted that in the aforementioned components, after the two bolts 409 penetrate the mounting part 410, they are fixed in both directions by the locking nut 411 located in the middle, effectively preventing the mounting part 410 from loosening under lifting tension or vibration. The bottom end of the locking nut 411 fits against the top end of the mounting part 410, enhancing the overall tightness and shear strength of the connection and improving the structural stress performance. This threaded locking method offers good adjustability and reusability, facilitating detailed adjustments according to different construction needs and enhancing the equipment's versatility and on-site adaptability.

[0079] Specifically, such as Figures 1 to 3 and Figure 10 As shown, the two side walls of the steel beam connecting and fixing device body 1 are provided with limiting grooves 301, and the inner walls of the two limiting grooves 301 are slidably connected with sliding supports 308.

[0080] It should be noted that in the aforementioned components, the limiting grooves 301 are located on both sides of the main body 1 of the steel beam connection and fixing device, serving as guide rails for the sliding support 308. This ensures that the sliding support 308 has a stable movement trajectory during structural installation or adjustment. This sliding connection structure can absorb construction errors, improve the degree of freedom of component docking, and limit its range of movement to prevent deviation from the design position. The sliding support 308, guided by the limiting grooves 301, allows for fine-tuning of components without additional tools, improving the overall assembly efficiency and stability of the structure.

[0081] Specifically, such as Figures 1 to 3 and Figure 10 As shown, sliding blocks 309 are fixedly connected to the outer sides of the two sliding supports 308, and a groove 306 is provided on the back of the mating plate 302, with the sliding blocks 309 slidably connected to the inner wall of the groove 306.

[0082] It should be noted that, in the aforementioned components, the cooperation between the sliding block 309 and the sliding groove 306 allows the docking plate 302 to move smoothly and precisely along the sliding path during installation, facilitating precise alignment by construction personnel according to the building structure. The fixed connection between the sliding support 308 and the sliding block 309 provides integrated structural support, improving the uniformity of force distribution on the sliding block 309 within the sliding groove 306, preventing localized friction or jamming, and ensuring smooth and stable operation of the docking plate 302 throughout the installation process. This structure further enhances the operational reliability of the auxiliary docking mechanism 3.

[0083] Specifically, such as Figures 1 to 3 and Figure 10As shown, an extension plate 314 is fixedly connected to one end of the docking plate 302. A threaded hole 312 is provided in the middle of the extension plate 314. A screw 310 is threadedly connected to the inner wall of the threaded hole 312. A scale plate 305 is fixedly connected to the top of the docking plate 302. A marking block 304 is fixedly embedded in the top of the detection plate 303.

[0084] It should be noted that in the above components, the extension plate 314 is set at one end of the docking plate 302 to extend the adjustment range of the connection structure. The threaded hole 312 on it provides a stable installation interface for the screw 310. The screw 310 achieves longitudinal advance and retreat adjustment through the threaded engagement with the threaded hole 312. It can be finely adjusted according to the actual docking error, so that the locking block 311 and the steel beam connection fixing device body 1 can fit more tightly. This adjustment structure is simple in design and precise in adjustment, which helps to ensure the smooth progress of the docking process and improves the adaptability and reliability of the steel beam connection fixing device body 1.

[0085] Specifically, such as Figures 1 to 3 and Figure 10 As shown, a locking block 311 is fixedly connected to one end of the screw 310, and the inner side of the locking block 311 is attached to the outer side of the steel beam connecting and fixing device body 1.

[0086] It should be noted that in the above components, the locking block 311 is fixedly connected to the end of the screw 310. When the screw 310 is screwed into the threaded hole 312 of the extension plate 314, the locking block 311 will gradually move closer to the body until it fits, realizing end positioning and locking. The locking block 311 fits against the outside of the steel beam connection and fixing device body 1, which can effectively prevent the docking plate 302 from sliding backward after adjustment, improving the connection stability. This structure can be locked directly by rotating the screw 310 without disassembling other components, which is simple and reliable, and further enhances the anti-interference ability and seismic performance of the steel beam connection and fixing device body 1.

[0087] Specifically, such as Figures 1 to 3 and Figure 10 As shown, a marking groove 313 is provided on the outer side of the docking plate 302, and the detection plate 303 is embedded in the inner wall of the marking groove 313.

[0088] It should be noted that in the above components, the marking groove 313 serves as the embedding channel for the detection plate 303, which can accurately limit the sliding direction of the detection plate 303 and provide a visual feedback window. When the detection plate 303 protrudes outward due to misalignment, its exposed part will be clearly visible from the marking groove 313, allowing construction personnel to quickly determine whether there is a deviation in the connection with the naked eye. This structure can achieve efficient detection without electronic sensors, is suitable for complex construction environments, and has the advantages of low cost, intuitive identification, and timely response. It is an important component of this invention to improve the accuracy and safety of the connection.

[0089] Working principle: The lifting auxiliary mechanism 4 is used to achieve efficient lifting and quick positioning of the steel beam connection and fixing device body 1. This lifting auxiliary mechanism 4 includes an adjusting rod 406, a locking plate 403, a base plate 413, a fixing seat 407, and a connecting piece 408. During use, it first connects to the lifting equipment via the connecting piece 408 at the top, such as by cooperating with a lifting hook, to achieve the overall lifting of the steel beam connection and fixing device body 1. The fixing seat 407 is located at the bottom end of the connecting piece 408 and is connected to the base plate 413 via the adjusting rod 406. The adjusting rod 406 is sleeved inside the base plate 413, facilitating fine adjustments in height or angle during lifting. The locking plate 403 is slidably connected. On the inner wall of the base plate 413, after the adjusting rod 406 is adjusted, the operator can push the locking plate 403 to slide along the sliding groove 402, and finally lock the position through the pin 404, ensuring that the entire mechanism is stable and reliable during lifting and positioning. At the same time, the pin 404 on the outside of the locking plate 403 passes through the base plate 413 and the locking plate 403, and the end of the pin 404 is vertically slidably connected to the locking rod 405. The operator only needs to insert or pull out the locking rod 405 to achieve quick installation and disassembly, which effectively improves construction efficiency. This structure can effectively avoid the safety hazards caused by inaccurate positioning or cumbersome adjustment during the traditional steel component hoisting process, and realize the quick and safe completion of the hoisting operation of the steel beam connection and fixing device body 1. The auxiliary docking mechanism 3 is specifically designed to assist in the precise docking and condition detection between steel beams and concrete column heads or building structures. This mechanism mainly includes a docking plate 302, a detection plate 303, and a back plate 307. The docking plate 302 is typically a pre-positioned component; during use, one side is first placed against the contact surface of the building or column head to ensure a preliminary installation position. The back of the docking plate 302 has a sliding groove 306, within which a sliding block 309 is slidably connected. The sliding block 309 is connected to a sliding support 308 and guides the docking plate 302 to move smoothly during installation via a limiting groove 301. Before docking is complete, the back plate 307 is in a free state, fixedly connected to one end of the detection plate 303 for detection. Plate 303 is slidably connected to the marking groove 313 in the middle of the mating plate 302. Under normal mating conditions, the back plate 307 should be completely attached to the building, and the detection plate 303 should remain concealed in the marking groove 313. However, if the mating is not good, such as if the column head is misaligned or the contact surface is tilted, the building may exert pressure on the back plate 307, causing the back plate 307 to deform or displace to a certain extent. This will cause the detection plate 303 connected to it to protrude along the marking groove 313. This structure can quickly determine whether the mating is in place by whether the detection plate 303 protrudes from the marking groove 313, thereby assisting construction personnel to adjust the installation position in time, avoiding problems such as misinstallation or incorrect installation, and improving the accuracy and safety of the mating process.
